Background

Surgical methods for heart valves generally include annuloplasty and valve replacement. A common surgical approach is generally through the median sternal incision and into the heart cavity after the pericardium is incised. Valve replacement is routinely required if the valve is severely damaged. The more commonly used prosthetic valves at present are mechanical and biological valves. The mechanical valve has a relatively long service life, but needs lifetime anticoagulation; bioprosthetic valves do not require lifelong anticoagulation, but have a relatively short service life. If the valve damage is not severe, repair of the valve and valvuloplasty may be considered. At present, in some large hospitals, cardiac surgery is better developed, and minimally invasive valve replacement or valvuloplasty can be performed under thoracoscopy, so that the relative trauma is much smaller.

The need for a vascular clamp during heart valve surgery is one means for surgeons to prevent blood flow to the surgical site and also to prevent blood vessel rupture or ruptured blood flow. Vascular clamps come in a variety of shapes and materials, typically high grade surgical stainless steel and durable plastics, with a flat, curved or serrated tip that clamps over the vein.
